To allwhom it my concern v Be/it known that-.1, MICHAEL citizen of the. United States, and a resident vALvE lion BOTTOM-DUMP cAas.

J. Owens, a

of Toledo, in the countyof Lucas and State of Ohio,, have invented -a certain new" anduseful Valve forBottom Dump Cars; and .I

do hereby declare the'following to be a full, clear, and enact description of the? invenfltion, such-as will enable others skilledin Referring to the drawings,

'gitudinal center the art towhich it appertains 'to make and use the SEIIXlQiIGfQI'BIlCd being had to the:

accompanyingdrawings, and tothe figures ofreferenceimarked thereon, which form a 1 part of, thisspecification.

dVIy invention [relates particularly to trucks or cars forjthe conveying of glassworks mlxlng materials, but 1s not rest-rlcted to'such use as it can be used in any conn' ec tion for which it isadap'tedorl appropriate.

The object of my invention is-the provision, in combination witha hopper'type', bottom dump, car. or'truck of this nature, of ajsimple and efficient form 'of valve for controlling a ,bottom discharge opening thereof, such: valve 'being" operable without the car and adapted to open upwardly' within] the car' and. the contents thereof, I

- Theinvention is fully described in'the following specification, and while, in its broader aspect, it is capable of embodiment innumerous forms, a preferred embodiment thereof is illustrated in the accompanying drawings, in which,%- i

.Figure 1 is a 'side elevati on of a car embodying my invention partly 1n sect-ion.

Fig.2 is" a. top plan view thereof-with a port-ionjimhorizontal section on a liner a: in Fig. 1. Fig. 3 is a vertical cross-section y in Fig. 1 with the valve in openposition, and Figs. 4 and 5 are different enlarged details of the [valve ad justing mechanism. I

1 designates a railroad car which'has its bottom provided. .in the present instance, adjacent-to the ionthereof, with-1a plurality of hopper-like discharge passages 2, the lower ends of which are open with.v the edges thereof contracted -"to form conical or tapered valve seats, as indicated at 3. These discharge passages are shown as being four and are arranged in pairs on in number, up os tely opposite sides of a transverse,

discharge end. These-valves are preferably, but not necessarily, of hollow or. shell-like thereof of conicalform to closely seat upon sages, as'shown. 8 A stem or red 7 pro ects upward from each valve 6 above'the car-top 8 and has the upper end portionthereof working through 1 a bushing member'9 in which it is threaded. as at 10, thus adapting a relative turning of the valve rod and bushing to-cfl'e'c'ta raising .orvlowering of the associated ,valve.

seats at its lower end upon a thrust-block or collar 11, which is supported within the any suitable manner, as by a turning of the.

bushing 9 upon its thrust-block.

fTo facilitate a raising of the .valves stood, however, that my invention is not limlted to any particular number of such. passages or- -tothe construction or arrange-.

A sleeve 14 en- 13 ,to the under side of the superimposed beams 12 to suspend the shell in, proper conical tops to deflect matter therefrom, and are shown as having interior rods 15, which project downward from top portions. 16 thereof and work through registeringapertures in the top of the valves to asgstin circles each valve rod 7 and rigidly connects the upper end of; the associated shell position within the car. The shells'13 haveguiding the movements of the valves and-{O 119 prevent arelative turning of the valves and shells. A suitable space is provided between the lower edge of each shell 13 and the sides of the associated discharge passage 2 to permit-a free flowing of the car contents through the passage When the valve is open, and the valve is of suitable length for its upper end to project a short distance'within the shell when the valve is seated. The

shells are braced relative to .the respective passages by braces 17-, which-are disposed intermediate the shells and passage walls.

It is apparent that I have provided simple andefi'ecient valve means for use in the discharge passages of cars adapted for the carrying of materials capable of flowing by gravlty, and that such means is'easily operable to open or,raise within the'car. con- "tentsto open the discharge passages:

I Wish it understood that-my invention is -not limited to any specific construction or arrangement of the parts except in so'faras such limitationsarespecified in. the claims. Having thus described my invention, I .25 Letters Patentis,.

What -I claim as new and desire to secure by L-In a car. having a bottom discharge stem projectingupward from the valve, a

e'ndthrust of. saidmember.

- 2. In a car havinga bottom discharge:

opening, a vertically elongated valve mov:

able withinthe car toopen and" close said .opening and a stationary superimposedguard shell into which the valve moves when opened, said shell having its top adapted for the deflection of loose matter therefrom.

3.- In a car having a bottom discharge opening, a valve vertically movable within the car to'open and close said opening, a

stem projecting upward from the valve, means operable to impart vertical move ments' to said'stem, and a stationary guard shell encircling portions ofrsai d stem and valve and into which the-valve works when raised and adapted to be entirely submerged in the car contents.

4. Ina car having a hopper-like discharge passage, a valve capable'of vertical move-- ments in said passage to open and close its outlet, a stem 'projecting'from the valve w thout theftop -po'rt-ion of the car,; and

guard means incasing portions of the stem 5. In a car having a bottom discharge passage, a cylindrical valve vertically movable within the. passage to open and close the same and havlng a stem projecting without the topportion of the car, rotatable andivalve and .telescopingwith' the valve. when raised.

means cooperating with said stem and i operable to efl'ect a raising and lowering guard part with 4 thereof, and a stationary which the valve telescopes.

6. In acar having a bottom discharge passage, a valve disposed within the car and having relatively movable parts, one of said parts-being vertically'movable to open-and.

close said. passage and the otherpart being stationary and serving asa' guard for the movable part,"and means operable above the --valve to move the movablelpart, said stationary parthaving its top disposed below the maximum contents height of the adapted to deflect matter therefrom.

7. In' a car having'tapering bottom. 01 tions terminating in a hopper-like bottom discharge opening having an internal conical valve seat, a valve for seating within said opening and vertically movable within the car, anda stationary guard shell-into which the valve moves when raised from seating position, said shell having parts cooperating with the. valve to 'prevent' a rela-'- car and tive. turning thereof and having a conical top for deflecting n'iat'tertherefrom.

8. In a 'car having a bottom discharge 'op ening,..-a valve vertically movable within" the car to openand' close said opening, a valve-control stem projectlng "upward from the valve, a stationary guardshell-into which the valve moves when raised, a hollow suspending stemprojecting upward from said shell through. which the valve stem worksy r and means supporting said hollow stem.

In testimony whereof, I "have hereunto. signed my name to thls spec'ifieatlon 1n the presence of two subscribmg -w1tnesses.
